ii6 LEPIDOPTERA. 



drab with a brouzy gloss; abdomen olive-brown, the segments 

 faintly edged with white. Fore wings elongated but decidedly 

 broad ; costa very gently arched ; apex squarely angulated ; 

 hind margin straight and almost perpendicular to near the 

 anal angle; bronzy-brown, with the median and all the 

 hinder nervures white dusted with brown, and minutely with 

 black ; just beyond the middle is a thick, erect, reddish-brown 

 transverse line, rather bent back near the costa ; near the hind 

 margin is a more slender, curved red-brown transverse line, 

 edgedoutwardlywithdull white; cilia red-brown, but so covered 

 with an intense golden gloss as to obscure the colour. Hind 

 wings very ample, rounded behind, pale smoky brown, 

 darker along the hind margin; cilia dull white. Female 

 similar, or paler. 



Underside of the fore wings smokj' black, the nervures 

 rather paler, the hind margin broadly j-ellowish-white, and 

 the dorsal margin somewhat whitened. Hind wings smoky 

 white. Body and legs bronzj'-brown. 



Usually not variable ; but a specimen taken near Brighton 

 by Mr. A. C. Vine is very strikingly white, the usual streaks 

 spreading so as to occupy much of the ground colour. 



On the wing in May and June. 



Lauva dull brown, with darker raised dots bearing each a 

 single dark hair; head honey-yellow, set with solitary hairs; 

 dorsal plate of the body-colour, narrow, deep set, and divided 

 by lighter colour. (Gartner.) Mr. Buckler says that the 

 newly hatched larva is greenish-grey with black-brown head 

 and dorsal plate, and the three hinder segments very pale. 



July till May on Fcstuca ovina and other grasses growing 

 in chalk soil, feeding in a silken tube at the roots. Mr. 

 Buckler's larvae from eggs do not seem to have advanced 

 beyond infancy. 



Pupa undescribed ; in a cocoon in the larva-tube, which is 

 attached to the lowest shoots of the grass stems. (Partner.)
